Jonas Veenhoven is a joint PhD student at Ghent University, the University of Amsterdam and the KIK-IRPA, the Royal institute for cultural heritage in Brussels Belgium. He focusses on the molecular characterisation of Asian lacquer natural polymers and the evaluation of cleaning approaches on those polymers using chromatography and mass spectrometry. The analysis of polymerised Asian lacquers is challenging due to the complex cross-linked matrices. Pyrolysis hyphenated with gas chromatography-mass spectrometry (Py-GC-MS) is suitable for the analysis of Asian lacquers and relies on the introduction of solid samples and online thermal decomposition of the lacquer polymer into small molecules amenable to GC-MS. In this contribution the stepwise application of progressive flash pyrolysis temperatures, ranging between 300-700 °C, is presented as a useful approach to differentiate between primary pyrolysis reactions and secondary dehydration products. This optimisation has shown to improve the characterisation of the polymeric compositions of Asian lacquers and to distinguish between the different, intermolecular covalent bonds.

Alessandra Marrocchesi graduated in 2019 with a Master’s degree in Physics from the University of Pisa. Since 2020 she is a PhD candidate at the University of Amsterdam within the EU-funded Marie Skłodowska-Curie Actions project Cultural Heritage Analysis for New Generations (CHANGE ITN). Her research focuses on the development of novel equipment and algorithms for the investigation of cultural heritage artifacts through technical photography.
